Warning over measles cases in US

US health officials have urged people to get vaccinated against measles after 13 cases were confirmed in Indiana

Holidaymakers planning to travel to the US have been urged to take out
medical travel insurance after a total of 13 measles cases were confirmed in Indiana.

The state's health commissioner Dr Gregory Larkin said the outbreak began last week when someone who was infected came into contact with someone who hadn't had the vaccine.

All cases are so far confined to the counties of Boone and Hamilton and only affect those who had direct contact with other infected people.

Health officials have now released a list of places where people may have caught the disease. This includes White River Elementary school and Noblesville Intermediate as well as Delphi Electronics and Safety in Kokomo.

A spokeswoman for the electronics company said employees had been informed about the risks.

Officials also said people who were born in the US before 1957 are likely to be immune, according to past research.

But everyone else - including those born outside of the US before 1957 - have been urged to take prompt action and arrange vaccination.
